Steel magnet body assembly

Abstract

A steel magnet body assembly comprises a first magnetizer ( 1 ) and a second magnetizer ( 2 ) that are magnetically conductive, and comprises multiple steel magnets ( 3 ). A magnetically insulative fixing member ( 4 ) used for fixing the steel magnets ( 3 ) is disposed between the first magnetizer ( 1 ) and the second magnetizer ( 2 ). The first magnetizer ( 1 ), the fixing member ( 4 ) and the second magnetizer ( 2 ) are sequentially stacked. The multiple steel magnets ( 3 ) are fixed in the fixing member ( 4 ) in an evenly spaced manner. Each steel magnet ( 3 ) is a column having an N magnetic pole and an S magnetic pole, and the N magnetic pole and the S magnetic pole of the steel magnets ( 3 ) are relatively disposed on two sides of a plane where the central axis of the column of the steel magnet ( 3 ) is located.
